(a) Porosity and (b) relative diffusion coefficient profiles of S. aureus biofilms relative to growth medium treated with vancomycin-only (Va), maltodextrin-only (Ma), or a combination of the two. Time in days indicates the age of the biofilm; treatments were administered after 5 days of growth. Porosity was not affected by the treatments, whereas maltodextrin caused a decrease in the relative diffusion coefficient. Data are means and error bars are standard deviation which represents heterogeneity within the biofilm domain
